Thanks, this is an unexpected behavior, because you are starting with
small amount of total memory exposed to a balloon at the beginning and
there should be no issues except if the inflation races with plugging
in new DIMMs (just a wild guess), dmesg output will be helpful there

Thanks Piotr, the lack of the host-side memory shrinkage after balloon
deflation is interesting anyway, hopefully you may share guest` dmesg
bits from compiled-in balloon to check visible signs of the issue
It is really hard to see dmesg output via vnc console, when kernel is sending
so many me

Hello.
Actually it was my mistake.
After some time using memory in guest (find /, cp bigfine, etc), res
size of qemu process shrinks to expected value.
Sorry for disturbing.
Now i don't see any memory waste in guest and host when using 'base'
memory + 'dimm' memory.
Although i have one issu

Would you mind to share you argument set to an emulator? As far as I
understood you are using plain ballooning with most results from above
for which those numbers are expected. The case with 5+gig memory
consumption for deflated 1G gues

Does it possible to get proper results with balloon ? For example by
patching qemu or something like this?
